The full ingredient list contains 44 items.

None of the 44 listed ingredients are sulfate based surfactants such as SLS or SLES (according to the version registered with the third party ingredient database Glowpick, checked 2026-08-28). The same ingredient list also includes fragrance, along with salicylic acid and titanium dioxide, and Glowpick itself flags 3 of these as medium to high risk. This ingredient list comes from a third party database and has not yet been cross checked item by item against the manufacturer's own label, so it is presented here as reported, without any claim of being irritation free or risk free.

ETUDE Soon Jung 2500ppm Weak Acidic Cleansing Mousse

ETUDE's Soon Jung 2500ppm Weak Acidic Cleansing Mousse belongs to the brand's Soon Jung line, which is aimed at sensitive skin. The formula is labeled as weakly acidic at pH 5.5 and is intended for sensitive, delicate skin. This mousse cleanser produces a dense, creamy foam without needing any extra foaming tool, making it a common entry point cleanser for sensitive skin at Korean beauty stores.

It can be purchased in Korea at the ETUDE official website, Olive Young stores, and ETUDE's own directly operated stores.

Mulgeo

Mulgeo is a Korean low irritation skin care brand whose product line is focused mainly on gentle cleansing. The specific products carried, their sizes, and their prices vary by store and by time period, so it's best to check the product name and price in person at an Olive Young store or on its website in Korea before purchasing.

Comparison Table and Where to Buy in Korea

During seasonal transitions or rosacea flare ups, it is not advisable to layer two or more cleansing products, such as a cleansing mousse and a cleansing balm, in a single face wash, nor to scrub the cheeks hard to generate a lot of foam. Even with a gentle cleanser, sensitive skin still calls for a light touch and a short washing time.
